Definitions

  • This invention relates to orthopedic appliances and, more particularly, to a system and method capable of gauging the degree of anteversion of the femur.
  • the joint replacement procedure may involve the use of a prosthesis which is implanted into one of the patient's bones.
  • a femoral prosthesis is implanted into the patient's thigh bone or femur.
  • One type of early femoral prosthesis was typically constructed as a one-piece structure having an upper portion which includes a spherically-shaped head which bears against the patient's pelvis or acetabulum, along with an elongated intramedullary stem which is utilized to secure the femoral component to the patient's femur.
  • the medullary canal of the patient's femur is first surgically prepared (e.g. reamed and/or broached) such that the intramedullary stem of the femoral prosthesis may be subsequently implanted therein.
  • the femoral prosthesis may be press fit into the medullary canal or, in the alternative, bone cement may be utilized to secure the femoral prosthesis within the medullary canal.
  • the anatomy of the bone into which the prosthesis is to be implanted may vary somewhat from patient to patient.
  • the patient's femur may be relatively long or relatively short thereby requiring use of a femoral prosthesis which includes a stem that is relatively long or short, respectively.
  • the stem in certain cases, such as when use of a relatively long stem length is required, the stem must also be bowed in order to conform to the anatomy of the patient's femur.
  • Such a need for prostheses of varying shapes and sizes can create a number of problems in regard to use of a one-piece prosthesis.
  • a hospital or surgery center must maintain a relatively large inventory of prostheses in order to have the requisite mix of prostheses needed for certain situations such as trauma situations and revision surgery.
  • the bow of the stem must conform to the bow of the intramedullary canal of the patient's femur, rotational positioning of the upper portion (i.e. proximal end) of the prosthesis is limited thereby rendering precise locating of the upper portion and hence the head of the prosthesis very difficult.
  • corresponding bones of the left and right side of a patient's anatomy e.g. left and right femur
  • a modular prosthesis is constructed in modular form so that the individual elements or features of the prosthesis can be selected to fit the needs of a given patient's anatomy.
  • modular prostheses have been designed which include a proximal neck component which can be assembled to any one of numerous distal stem components in order to create an assembly which fits the needs of a given patient's anatomy.
  • a proximal neck component which can be assembled to any one of numerous distal stem components in order to create an assembly which fits the needs of a given patient's anatomy.
  • Such a design allows the distal stem component to be selected and thereafter implanted in the patient's bone in a position which conforms to the patient's anatomy while also allowing for a limited degree of independent positioning of the proximal neck component relative to the patient's pelvis.
  • three components in addition to the head are utilized: a distal stem component that is engaged within the femur, a proximal metaphyseal filling component, and an intermediate neck component that supports the head component on the distal stem component.
  • the provision of three components has greatly increased the degree of flexibility in producing a total hip implant that most closely approximates the patient's skeletal anatomy and normal joint movement.
  • One such system is the S-ROM® total hip system marketed by DePuy Orthopaedics, Inc.
  • the S-ROM® total hip system offers neck and head components having different lengths, different lateral offsets of the neck relative to the stem, as well as different stem configurations.
  • trial implants In order to properly size the final implant, many systems utilize trial implants, commonly referred to as simply trials.
  • modular systems such as the S-ROM® instrument system, neck trials, proximal body trials, distal stem trials, head trials and sleeve trials can be provided.
  • Each trial is provided in a number of sizes and geometries to give the surgeon a wide range of combination from which to choose.
  • the trials afford the orthopaedic surgeon the opportunity to assess the fit and position of a final implant without having to complete the fixation.
  • the trials are modular to reduce the inventory of components and the complexity of the trialing process.
  • the anteversion angle is an angle of rotation between the ball end of the femur and the plane of the intramedullary canal of the bone.
  • the anteversion angle is the relative angular rotation of the proximal neck component relative to the distal stem component. Proper rotational position, or anteversion angle, allows for accurate and stable reproduction of the mechanical orientation and function of the reconstructed hip joint.
  • the proper anteversion angle can be obtained by simply spinning the distal stem within the prepared bore in the femur. In a typical case, the surgeon can visually evaluate the orientation of the proximal body relative to the surrounding anatomy. If a trial is used, the trial is removed and the final prosthesis is implanted as close to the trial position as possible. Sometimes, x-rays are used to verify the rotational alignment, while some systems rely upon external references to verify alignment.
  • the S-ROM® total hip system described above utilizes laser markings on the proximal end of the distal stem and on the proximal sleeve. These markings enable the surgeon to measure relative anteversion rotational alignment between the components. Since the sleeve has infinite anteversion it is not necessarily oriented relative to a bony landmark that can be used to define the anteversion angle. In fact, for simplicity, most current sleeves are oriented with the laser marking pointing directly laterally into the remaining available bone of the femur.
  • the modular system includes a curved distal stem.
  • a long distal stem is utilized, it must be curved to follow the natural shape of the femur.
  • the rotational alignment of a curved stem cannot be modified once the curved stem is implanted.
  • the anteversion is determined by using a variety of trial femoral heads which allow a surgeon to vary the position of the head center along the axis of the neck thereby altering the head offset in both the horizontal and vertical directions simultaneously.
  • Other systems provide a combination of trial femoral heads with two or three trial neck components that allow pure horizontal variability. Some systems even offer independent horizontal and vertical control in addition to the effects of the trial heads.
  • the anteversion angle in known systems can be changed in either discrete, indexable jumps (e.g., 10 degree increments) or with infinitely fine, continuous movement.
  • the precision of systems using discrete jumps is limited by the size of the jump. This presents a limitation in that even rotational changes on the order of about 5 degrees can appreciably affect impingement, dislocation rate, and the range of motion of a joint.
  • the systems that provide infinitely fine, continuous movement overcome the limitation of using discrete angles.
  • the continuous movement systems are also limited. Specifically, once the configuration of the trial has been established, it is necessary to perform a trial reduction of the joint to verify that the optimum configuration has been achieved.
  • Prior art continuous movement systems do not provide a sufficiently strong coupling between the trial and the distal body. Accordingly, the continuous movement systems frequently fail to hold rotational stability during the trial reduction. This requires the anteversion to be re-established and another trial reduction performed, prolonging the surgical procedure.
  • a proximal trial to be attached to a distal body with a full 360 degree freedom of rotation and which provides for sufficient stability to resist trial failure.
  • a system and method for trialing a modular hip replacement system permits evaluation and replication of the anatomic anteversion rotational angle of the femur.
  • a femoral hip implant kit includes at least one distal implant and a plurality of femoral heads, each of the plurality of femoral heads having a diameter different from the diameter of the other of the plurality of femoral heads.
  • the kit includes a proximal trial housing with a bore within the housing, the bore configured to receive a portion of the distal implant, a collet located within the bore, the collet including an outer wall portion extending between a top surface portion and a bottom surface portion, a collapsing member for engaging the portion of the distal implant and for forcing the top surface portion of the collet toward the bottom surface portion of the collet along a first axis, thereby forcing the outer wall portion in a direction generally perpendicular to the first axis such that the outer wall portion is located outwardly of the top surface portion and the bottom surface portion with respect to the first axis.
  • a femoral hip implant proximal trial in another embodiment, includes an housing and a bore within the housing that is configured to receive a portion of a distal implant.
  • a resiliently collapsible collet is located within the bore and a collapsing member engages the portion of the distal implant and is operable to resiliently collapse the collet within the bore such that the collet is resiliently pressed against the wall of the bore, so as to angularly lock the housing with the distal implant.
  • One method in accordance with the invention includes providing a bore within a proximal trial housing, receiving a portion of a distal implant within the bore, engaging the portion of the distal implant with a collapsing member, and moving an upper portion of the collet closer to a bottom portion of the collet along a first axis.
  • the method includes forcing an outer wall portion of the collet in a direction generally perpendicular to the first axis in response to the moving of the upper portion of the collet; and contacting the wall of the bore with the outer wall portion of the collet such that the distal implant is angularly locked to the proximal trial housing.

The counter-clockwise rotation causes the nut 106 to move upwardly, away from the rim 144 . This allows the collet 154 to elastically decompress. The decompression of the collet 154 continues until the nut 106 is no longer compressing the spring washer 166 , thereby removing the angular lock between the distal trial stem 102 and the proximal trial body 104 .
  • the angle between the distal trial stem 102 and the proximal trial body 104 may be modified.
  • one or more trial components may be replaced, or the angle between the distal trial stem 102 and the proximal trial body 104 may be altered and a subsequent trial reduction performed.
  • the modular trial assembly 100 may be removed and replaced with permanent implants mimicking the configuration of the modular trial assembly 100 . This is accomplished by continued rotation of the nut 106 in the counterclockwise direction until the upper threaded portion 118 of the distal trial stem 102 is no longer engaged with the threaded portion 164 .
  • the proximal trial body 104 is then removed from the distal trial stem 102 by moving the proximal trial body 104 upwardly until the flange 124 contacts the spring 170 forcing the spring 170 into the cavity 140 .
  • the proximal trial body 104 is then separated from the distal trial stem 102 .
  • FIG. 9 shows an alternative proximal trial body 180 .
  • the proximal trial body 180 is shown with a nut 182 that includes a lower portion 184 that is configured to engage a collet 186 in order to angularly lock the proximal trial body 180 with a distal implant 188 .
  • the collet 186 includes an upper portion 190 and a bottom portion 192 separated by a wall 194 .
  • a plurality of ribs 196 are located about the wall 194 .
  • the upper portion 190 and the bottom portion 192 define openings 198 and 200 (see FIG. 11 ), respectively.
  • the upper portion 190 is configured to be generally complementary with the lower portion 184 of the nut 182 .
  • the openings 198 and 200 are configured to be just slightly larger in diameter than the portion of the distal implant 188 that extends through the collet 186 as shown in FIG. 9 .
  • FIGS. 9-11 The embodiment shown in FIGS. 9-11 is operated in much the same manner as the modular trial assembly 100 of FIG. 1 .
  • One difference is that as the collet 186 is collapsed, the ribs 196 provide the binding contact with the proximal trial body 180 . Additionally, the resilient deformation of the collet 186 causes the openings 198 and 200 to bind with the distal implant 188 providing a frictional lock in addition to the frictional lock between the nut 182 and the distal implant 188 . Accordingly, a strong angular lock between the distal implant 188 and the proximal trial body 180 is achieved.
  • the proximal trial body 210 includes a main bore portion 212 and a lower bore portion 214 .
  • a collet 216 is located within the main bore portion 212 .
  • the collet 216 includes a bottom portion 218 , a top portion 220 and an outer wall 222 .
  • a nut 224 is also located within the main bore portion 212 .
  • the broach 226 which is used with the proximal trial body 210 includes an expandable flange 228 and a threaded portion 230 .
  • the flange 228 is configured to expand within the main bore portion 212 of the proximal trial body 210 .
  • the collet 216 is compressed between the nut 224 and the expandable flange 228 .
  • the bottom portion 218 of the collet 216 is not symmetrical with the top portion 220 . This is because the bottom portion 218 is configured to extend only partially over the lower bore portion 214 while the outer wall 222 of the collet 216 extends outwardly of the lower bore portion 214 when the collet 210 is not compressed.
  • the outer wall 222 prevents the collet 216 from falling through the lower bore portion 214 when the broach 226 is not inserted within the proximal trial body 210 .
  • the partial extension of the bottom portion 218 over the lower bore portion 214 allows the threaded portion 230 of the broach 226 to pass through the collet 216 while ensuring that the flange 228 entraps the collet 216 between the flange 228 and the nut 224 when the flange 228 is inserted into the main bore portion 212 .
  • the collet 216 does not have ribs.
  • the outer wall 222 of the collet 216 is slightly curved in an outwardly direction when the collet 216 is in an uncompressed state.
  • the surface area of the wall 222 that contacts the wall of the main bore portion 212 increases.
  • the proximal trial body 234 includes a main bore portion 236 and a lower bore portion 238 separated by a lip 240 .
  • a collet 242 is located within the lower bore portion 238 .
  • the collet 242 is similar to the collet 216 .
  • a nut 244 is also located within the main bore portion 236 .
  • the reamer 246 which is used with the proximal trial body 234 includes an expandable flange 248 and a threaded portion 250 .
  • FIG. 13 works similarly to the embodiment of FIG. 12 .
  • the main difference is that the collet 242 is compressed between the flange 248 and the lip 240 .
  • the nut 244 compresses the collet 242 indirectly.
